Abstract
The utility model provides a car front seat headrest, includes metal framework, the cladding expanded material outside metal framework to and the headrest cover of cladding outside expanded material, still include the display screen, metal framework is the U -shaped steel pipe, expanded material includes from the interior foaming layer of high density polypropylene, the foaming layer of low -density polypropylene and the polyurethane foam layer that sets up to outer order, the back on the polyurethane foam layer is equipped with the vallecular cavity, and the display screen is installed in this vallecular cavity. The utility model discloses multimedia functions such as amusement and back seat navigation have been increased, fall into two kinds of density to the density of foaming polypropylene skeleton, improved the travelling comfort of headrest under the condition that does not influence structural strength, direct bonding was in the same place when foaming polyurethane was the shaping with the foaming polypropylene, and the holistic performance of resting the head on uses assembly combination's mode higher than before, and the processing assembly is simpler, the cost is lower.
Description
Technical field
The utility model relates to automobile component, particularly relates to a kind of front-row seats of vehicle headrest.
Background technology
Main injection moulding skeleton, metallic framework, polyurathamc, the leather of using of the front-row seats of vehicle headrest of prior art reinforces locking member and little functor composition.Fraction vehicle replaces injection moulding skeleton and polyurathamc with common expanded polypropylene, and applied foam polyurethane is coated again.
The first scenario-frame above-mentioned is complicated, feed stock cost and assembly cost high.Poor safety performance.Although first scheme structure is simple, because common expanded polypropylene skeleton instead of injection moulding skeleton and partial foaming polyurethane, improve cushion characteristic when impacting.Headrest overall weight declines.But because expanded polypropylene needs the effect playing bracing frame, density generally can not be too low, and therefore the traveling comfort of passenger is not very desirable.
Utility model content
The purpose of this utility model, exactly in order to solve the problem, provides a kind of novel front-row seats of vehicle to rest the head on.
In order to achieve the above object, the utility model have employed following technical scheme: a kind of front-row seats of vehicle headrest, comprises metallic framework, the expanded material be coated on outside metallic framework, and is coated on the head rest cover outside expanded material; Also comprise read-out; Described metallic framework is U-shaped steel pipe; Described expanded material comprises high density poly propylene foaming layer that order from the inside to the outside arranges, low density polypropylene foaming layer and polyurethane foaming layer; Be provided with vallecular cavity at the back side of polyurethane foaming layer, described read-out is arranged in this vallecular cavity.
Described head rest cover is provided with the hole with described vallecular cavity adaptation, and the injection moulding card article on edge, hole is provided with for being stuck in bottom vallecular cavity high density poly propylene foaming layer.
Be connected with wire harness in described U-shaped steel pipe, this wire harness passes from U-shaped steel pipe top, and the corresponding passage be provided with for passing wire harness in described high density poly propylene foaming layer, described wire harness passes from this passage and telecom-connects with described read-out.
The density of described low density polypropylene is 30kg/m
3.
The density of described high density poly propylene is 40-50kg/m
3.
High density poly propylene foaming layer bottom described vallecular cavity is provided with multiple velcro, and described read-out is pasted with velcro and is connected.
Described read-out comprises LCDs or touch screen flat panel computer.
Compared with prior art, the utility model has the following advantages:
1, the multimedia function such as amusement and back seat navigation is increased.LCDs or touch screen flat panel computer can be used.Rear row passenger is auxiliary sees navigation, video display and MP4 etc.
2, the high strength expanded polypropylene used effectively reduces the weight of headrest in identical performance than common expanded polypropylene.
3, the density of expanded polypropylene skeleton being divided into two kinds of density, improving the traveling comfort of headrest when not affecting structural strength.
4, be directly bonded together when polyurathamc and expanded polypropylene are shaping, the Performance Ratio of headrest entirety used the mode of assembly higher originally, and process and assemble is simpler, cost is lower.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present invention.
Detailed description of the invention
See Fig. 1, front-row seats of vehicle of the present utility model headrest, comprises metallic framework 1, the expanded material be coated on outside metallic framework, and is coated on the head rest cover 5 outside expanded material; Also comprise read-out 6; Above-mentioned metallic framework is U-shaped steel pipe; Expanded material comprises high density poly propylene foaming layer 2 that order from the inside to the outside arranges, low density polypropylene foaming layer 3 and polyurethane foaming layer 4; Be provided with vallecular cavity at the back side of polyurethane foaming layer, read-out 6 is arranged in this vallecular cavity.Wherein, the density of low density polypropylene is 30kg/m
3, the density of high density poly propylene is 40-50kg/m
3.High density poly propylene foaming layer bottom vallecular cavity is provided with multiple velcro 9, and read-out is pasted with velcro and is connected.
Head rest cover 5 in the utility model is provided with the hole with above-mentioned vallecular cavity adaptation, and the injection moulding card article 7 on edge, hole is provided with for being stuck in bottom vallecular cavity high density poly propylene foaming layer.
Be connected with wire harness 8 in U-shaped steel pipe in the utility model, this wire harness passes from U-shaped steel pipe top, and the corresponding passage 21 be provided with for passing wire harness in high density poly propylene foaming layer 2, described wire harness 8 passes from this passage and telecom-connects with read-out.
Read-out in the utility model comprises LCDs or touch screen flat panel computer.
Manufacturing process of the present utility model is, first cuts the steel pipe of certain length, is then bent into U-shaped shape, then inside dual density foaming mould steel pipe being embedded in particular design, then is injected into SEPP bead and is molded into EPP head rest body.SEPP divides two parts, near the use lower density (30kg/m of head of passenger
3) SEPP material, all the other positions use high density (40-50kg/m
3) SEPP material.Point part processed is embedded PUR foaming mould, and injection PUR material, PUR foaming is directly attached on formation entirety on EPP.Finally the head rest cover processed is enclosed within body, head rest cover has a circle injection moulding card article around read-out opening part, the flange of leather sheath is pressed on the groove of EPP body.Read-out uses velcro to be fixed on EPP body, is convenient to dismantle when user keeps in repair.Data line is passed from steel pipe, connects on a display screen, then read-out is stuck on headrest.
